§ 4370m–4. Coordination of required reviews
(a) Concurrent reviews
To integrate environmental reviews and authorizations, each agency shall, to the maximum extent practicable—
(1) carry out the obligations of the agency with respect to a covered project under any other applicable law concurrently, and in conjunction with, other environmental reviews and authorizations being conducted by other cooperating or participating agencies, including environmental reviews and authorizations required under NEPA, unless the agency determines that doing so would impair the ability of the agency to carry out the statutory obligations of the agency;
(2) formulate and implement administrative, policy, and procedural mechanisms to enable the agency to ensure completion of the environmental review process in a timely, coordinated, and environmentally responsible manner; and
(3) where an environmental impact statement is required for a project, prepare a single, joint interagency environmental impact statement for the project unless the lead agency provides justification in the coordinated project plan that multiple environmental documents are more efficient for project review and authorization.
(b) Adoption, incorporation by reference, and use of documents
(1) Use of existing documents
(A) In general

(A) a significant change has been made to the covered project that is relevant for purposes of environmental review of the project; or
(B) there has been a significant circumstance or new information has emerged that is relevant to the environmental review for the covered project.
(4) Comments
If a lead agency prepares and publishes a supplemental document under paragraph (3), the lead agency shall solicit comments from other agencies and the public on the supplemental document for a period of not more than 45 days, beginning on the date on which the supplemental document is published, unless—
(A) the lead agency, the project sponsor, and any cooperating agency agree to a longer deadline; or

With the concurrence of the cooperating agencies with jurisdiction under Federal law and at the discretion of the lead agency, the preferred alternative for a project, after being identified, may be developed to a higher level of detail than other alternatives to facilitate the development of mitigation measures or concurrent compliance with other applicable laws if the lead agency determines that—
(A) the development of the higher level of detail will not prevent the lead agency from making an impartial decision as to whether to accept another alternative that is being considered in the environmental review; and
(B) the preferred and other alternatives are developed in sufficient detail to enable the public to comment on the alternatives.
(d) Environmental review comments
(1) Comments on draft environmental impact statement
For comments by an agency or the public on a draft environmental impact statement, the lead agency shall establish a comment period of not less than 45 days and not more than 60 days after the date on which a notice announcing availability of the environmental impact statement is published in the Federal Register, unless—
